Interface Configuration

You can modify the interface configuration in the "Dashboard" without changing the front-end code. Additionally, configuration files and environment variables are also supported.

The priority of interface configuration is as follows:

Environment Variables > Configuration File = Dashboard > Front-end Code

Configuring the Interface via `Artalk.init`

When initializing with Artalk.init on the front-end page, pass parameters to configure the interface. Below are all the available configuration options.

const artalk = Artalk.init({
  el:        '#Comments',
  pageKey:   '/post/1', 
  pageTitle: 'Page Title',
  server:    'http://your_domain:8080',
  site:      'Artalk Blog',
})

// Update configuration
artalk.update({ ... })
